“God had made
To our ancestors,
And to his descendants,
καθὼς ἐλάλησεν πρὸς τοὺς πατέρας ἡμῶν, τῷ Ἀβραὰμ καὶ τῷ σπέρματι αὐτοῦ εἰς τὸν αἰῶνα.
This canticle of Mary concluded by remembering the promises that God had made to their ancestors, especially to Abraham in Genesis, chapters 12:3, 15:5, 17:7, 18:18, and 22:17. and his eternal descendants. Notice that there is no mention of Jacob, Moses, or David, but the wider Abraham covenant. Luke indicated that Mary said that God had spoken (καθὼς ἐλάλησεν) to their ancestors (πρὸς τοὺς πατέρας ἡμῶν), to Abraham (τῷ Ἀβραὰμ), and to his descendants (καὶ τῷ σπέρματι αὐτοῦ) for all time or forever (εἰς τὸν αἰῶνα).
